Can I attend only part of the class?
Yes. However, we recommend that you be present for the entire class, so you don't miss some of the great questions asked by class attendees and information not included in the handouts such as examples and scenarios to the taxability of certain transactions. We require pre-registration for all classes and will reserve your spot for the entire class session.

I can’t stay for the entire class. Can I leave early?
You can choose to leave early; however, if you need to take the class again, just go back to the Online Class Registration link.

Is CPE (Continuing Professional Education) Credit offered for every class?
Yes, CPE credit is available for all classes unless otherwise stated.

Is it too late to register for a class?
If a class is FULL to capacity, you will not be able to register for that class and the automated system will inform you that it is FULL.

Will I receive confirmation of my reservation?
No. Once registered, every class you are signed up to attend will appear in Your Schedule in the online registration system.

I have a new business. What classes should I take?
We offer a wide range of topics/classes that are beneficial to both new and existing businesses. Please refer to the Workshops and Education Web Page for all topics and descriptions, as we have classes for those who are new to sales/use tax in Colorado to those that focus on industry specific issues. When taking advanced classes, it is recommended that you take the Sales/Use Tax Class Part I or you have a good understanding of sales/use tax laws in Colorado.

I can’t attend any of the current class offerings. Can I register for a class that is not posted yet?
Registrations are accepted only for the current classes listed on the Main Class Schedule. However, classes are offered every month at different locations, so please continue to check back for updated class listings. If you cannot attend a tax class but need assistance with the Colorado Sales Tax and Withholding Application (CR 0100), you can either use Colorado Business Express which will allow you to open your account online, or contact our call center (303) 238-7378, Monday – Friday, from 8:00 a.m. to 4:30 p.m. If you need assistance with completing the Colorado Sales Tax Return (DR 0100), file the return in Revenue Online, or refer to the Sales Tax Return (DR0100) Tutorial.

Where are your classes held?
Classes are held throughout Colorado but mainly in the Metro Denver Area, Colorado Springs, Fort Collins, Pueblo and the Western Slope. Since many different topics are offered, be sure to check the class descriptions before attending a class to ensure the class meets your needs.

I missed the Metro area class in my location. Now what can I do?
You may attend any class in any city we are currently holding the class. If you cannot attend in that city, you also have the option of viewing all of our live classes in an online format. You can view these classes on our Class Content Online Web page.

Will the Metro area classes be held again at my preferred location?
Yes. However, you’ll need to check back, as schedules of classes are posted when all details for those classes are confirmed. Check the Online Class Registration Web site regularly to see when we are returning to your area. Or, you have the option of viewing all of our live classes in an online format.

Do I have to attend the Sales/Use Tax Class Part I prior to attending the Sales/Use Tax Class Part II?
We recommend that your take the Sales/Use Tax Class Part I if you have no sales/use tax knowledge or are new to Colorado sales/use tax. You are welcome to attend any class offering at any time, but keep in mind when attending the Sales/Use Tax Part II class, the Use Tax class and the industry specific classes, terms are used that you may not be aware of, so having sales/use tax knowledge before attending those classes will be helpful.

I noticed that limited class topics are offered outside the Metro Denver. Do I have to come to Denver to take classes on other topics?

At this time, the Sales/Use Tax Part I class is the only live class offered in Colorado Springs, Fort Collins and the Western Slope. However, we offer many class topics in various online formats. See the Workshops and Education page for other available fomats.
